Rails 4 warnings: already initialized constant Racc::Parser:: etc..

[taboularasa]

Hello, I'm getting a bunch of warnings after including phys-units in my Rails 4 project. Do any of these look familiar to you? Wondering if I should look into this or ignore it. I'm not getting anything helpful from searching the internet so far.

Phys-units seems to be working fine and I haven't encountered any side effects elsewhere in the app (although I just added the gem so maybe I'll see some problems later)
